Objective To explore differentially expressed proteins in the serum exosomes of acute myeloid leukemia(AML)patients and healthy controls by using the proteomics method,and provide new biomarker for the diagnosis and treatment of AML.Methods A total of 76 AML patients diagnosed and treated in the First People's Hospital of Honghe State from November 2022 to June 2024 were selected as the experimental group,and 60 healthy physical examination participants were selected as the control group.Tandem Mass Tag(TMT)labeled proteomics was used to identify the differences in protein expression in serum exosomes between the experimental and control groups,and the identified differentially expressed proteins were subjected to bioinformatics analysis.Western-Blot was used to verify the differentially expressed proteins.Results Comparedwith healthy controls,146 aberrantly expressed proteinswere detected in serum exosomes of AML patients,of which 89 were up-regulated and 57 were down-regulated.Among them,Alpha-1-antichymotrypsin(α1-ACT),Angiogenin(ANG),Vitronectin(VIT),Clusterin(Clu),Fibronectin(FN),Keratin type I cytoskeletal-18(KRT18),and actinin alpha4(ACTN4)showed changed significantly.Gene ontology(GO)and Kyoto encyclopedia of genes and genomes(KEGG)enrichment analysis indicated that differentially expresseproteins were involved in biological processes such as neutrophil immunity,neutrophil degranulation,neutrophil activation immune response,and protein activation cascade,significantly enriched in 25 biological pathways including complement and coagulation cascades,extracellular matrix(ECM)-receptor interaction,and hypoxia-inducible factor-1(HIF-1)signaling pathways.Western-blot validation results showed that compared with the control group,the expression levels of ANG,Clu and FN in the serum exosomes of AML patients were significantly increased,while the expression level of ACTN4 was significantly decreased,with statistically significant differences(t=-11.854～18.569,all P<0.05).The expression levels of ANG and FN were correlated with white blood cell count(F=8.888,7.818,all P<0.05)and cytogenetics(F=8.619,7.983,P<0.05).The expression level of Clu protein was correlated with white blood cell count(F=2.571,P<0.05),but not significantly associated with cytogenetics(F=1.886,P>0.05).ANG,FN and Clu showed no significant correlation with FAB classification(F=0.175,0.434,0.042,all P>0.05).Conclusion The expression of exosomal proteins in the serum of AML patients compared to healthy individuals are significant differences,which may serve as serological markers for the diagnosis and treatment of AML.

Aging is an inevitable, physiological process of the human body, leading to deterioration in bodily function and increased susceptibility to various diseases. Effective endogenous therapeutic strategies for anti-aging and related diseases remain limited. Exercise confers multifaceted benefits to physical health by augmenting osteogenic and myogenic processes, enhancing cardiovascular and nervous system function, and attenuating chronic inflammation. Angiogenesis and lymphangiogenesis play pivotal roles in anti-aging, tissue repair, and immune response modulation, underscoring their potential as therapeutic targets for age-related diseases. Modulating angiogenic and lymphangiogenic pathways may provide a promising strategy for mitigating vascular decline and immune system dysfunction associated with aging. Exercise-induced endogenous angiogenesis and lymphangiogenesis can exert beneficial effects on physiological function, thereby representing a potential therapeutic paradigm for combating age-related decline and diseases. This review offers a thorough summary of the present knowledge regarding angiogenesis and lymphangiogenesis induced by exercise, encompassing the underlying mechanisms and the effects in different organs. In addition, it explores the potential of physical activity as a non-pharmacological intervention for anti-aging strategies and disease management, offering novel insights into the intersection of physical activity, aging, and disease progression.

Varicella is a common infectious disease caused by varicella-zoster virus (VZV), with high transmissibility and pathogenicity, and vaccination is a better preventive measure. The clinical diagnosis of varicella, the clinical immunogenicity evaluation of varicella vaccine, the continuous monitoring of the immune effect after marketing and the epidemiological investigation all require the detection of the antibody level of VZV in patients. Fluorescent antibody to membrane antigen method (FAMA) is the gold standard for detection of VZV antibody in serum, possessing advantages of high sensitivity and good specificity, playing an important role in detection of VZV antibody. However, the defects of FAMA operation complexity and low throughput are also troubling the clinical testing personnels. This article reviews research progress both at home and abroad on the technology of VZV serum antibody detection. The advantages and limitations of the current detection methods are discussed and the future development direction are highlighted on the dectection of VZV serum antibody IgG.

A case of sarcomatoid renal cell carcinoma was reported. After admission，laparoscopic radical right nephrectomy was performed without postoperative radiotherapy，chemotherapy or immunotherapy. Five months after operation，the tumor recurred，with lung metastasis and tumor thrombus formation in inferior vena cava. Sarcomatoid renal cell carcinoma is extremely rare clinically，with high malignancy，poor prognosis，atypical symptoms，and no specificity in auxiliary examination. CT is the first choice of examination. At present，the diagnosis is mainly by pathological examination and immunohistochemical staining. The treatment of this disease depends mainly on early surgical resection，and it is not sensitive to radiotherapy or chemotherapy.

Objective: To understand the occurrence and predictive factors of depressive symptoms among multi ethnic middle school students in Yunnan Province, so as to provide a referential framework for schools to carry out targeted mental health education. Methods: From October to December 2022, 8 500 first grade students from 23 middle schools were selected from 11 minority areas in Yunnan Province by cluster random sampling method. Demographic information and data relating to the students lifestyles were collected by questionnaire, and the Children s Depression Inventory (CDI) was used to evaluate depressive symptoms. Chi square test was performed to compare differences in the detection rate of depressive symptoms among first grade middle school students for univariate analysis. A decision tree model of depressive symptoms in middle school students was established by using the Chi squared automatic interaction detector (CHAID). Results: The detection rate of depressive symptoms among first grade students from multi ethnic middle schools in Yunnan Province was 28.26%. The decision tree model of depressive symptoms was academic stress ( χ 2=469.08) at the first level, breakfast behaviors (low/moderate academic stress: χ 2=155.49; severe academic stress: χ 2=105.24) at the second level, and the number of close friends (low/moderate academic stress and consuming breakfast 0- 2 days weekly: χ 2=23.15; low/moderate academic stress and consuming breakfast 3-4 days weekly: χ 2=14.99; severe academic stress and consuming breakfast 0-2 days weekly: χ 2=29.26; severe academic stress and consuming breakfast 3-4 days weekly: χ 2=20.15), ethnicity ( χ 2=78.22) and drinking ( χ 2=50.36) at the third level ( P <0.01). Conclusions The study identifies academic stress, breakfast behaviors, number of close friends, drinking and ethnicity as predictive factors of depressive symptoms among multi ethnic middle school students in Yunnan Province. Schools should develop targeted strategies for preventing and managing depressive symptoms in middle school students, so as to reduce their occurrence.

Objective: To investigate the association of sugar sweetened beverage (SSB) consumption with insomnia and depressive symptoms among first grade middle school students from Yunnan Province, so as to provide evidence to guide interventions for the treatment of these symptoms in this population. Methods: From October to December 2022, 8 500 firstgrade middle school students from 11 counties in Yunnan Province were selected by cluster random sampling. Depressive symptoms, SSB consumption, and insomnia symptoms among students were evaluated by the Child Depression Scale (CDI), dietary frequency questionnaire, and Insomnia Severity Index (ISI). A Logistic regression model was employed to analyze the relationship between SSB consumption, insomnia, depressive symptoms, and their interaction effects among students. Results: The detection rate of depressive symptoms was 28.3%, and having insomnia symptoms ( OR=6.07, 95%CI =5.46-6.75), consuming carbonated beverages ( OR=1.20, 95%CI =1.08-1.34), tea ( OR=1.13, 95%CI =1.02-1.25), energy drinks ( OR=1.36, 95%CI =1.23-1.50), and other beverages ( OR=1.32, 95%CI =1.19-1.45) were positively correlated with depressive symptoms among first grade middle school students ( P < 0.05). Carbonated beverages (additive effect: OR=2.96, 95%CI =2.72-3.22, multiplicative effect: OR=4.75, 95%CI =4.25- 5.32 ), fruit drinks (additive effect: OR=2.61, 95%CI =2.40-2.82; multiplicative effect: OR=4.43, 95%CI =3.94-4.97), tea (additive effect: OR=2.70, 95%CI =2.47-2.89; multiplicative effect: OR=4.34, 95%CI =3.86-4.89), energy drinks (additive effect: OR=2.82, 95%CI =2.61-3.05; multiplicative effect: OR=4.48, 95%CI =3.92-5.12), sweetened milk (additive effect: OR= 2.73, 95%CI =2.06-2.96; multiplicative effect: OR=4.61, 95%CI =4.12-5.17) and other beverages (additive effect: OR= 2.73 , 95%CI =2.53-2.95; multiplicative effect: OR=4.56, 95%CI =4.00-5.20) had both additive and multiplicative effects with insomnia, and increased the risk of depressive symptoms in first grade middle school students ( P <0.01). Conclusions The interaction between the consumption of SSB and insomnia symptoms may increase the risk of depressive symptoms among first grade middle school students in Yunnan Province. It is necessary to advocate middle school students to reduce SSB intake, in order to decrease the occurrence of depressive symptoms among this population.

Caprine enterovirus(CEV)is one of the most important infectious diarrheal diseases for goats.In order to understand the prevalence of CEV in different areas of Jiangsu province,410 goat fecal samples(212 diarrhea and 198 non-diarrhea samples)were collected from goat farms in 8 re-gions.127 CEV positive samples were detected by RT-PCR,and the positive rates varied greatly from 12.50％to 62.50％among different areas,with a total positive rate as 30.98％.Through the significance analysis of the positive rate of diarrhea and non-diarrhea samples,CEV was found to be one of the important pathogens causing diarrhea in goats.The results of homology and genetic evolution analysis for the 5'-UTR sequences showed that the EV-G5、G7、G21、G22 and G23 were epidemic types in Jiangsu province,and G21-G23 are new found CEV types.The homologies of 5'-UTR,VP1 and 2AB genes with the classical CEV strains in China were 78.6％-95.8％,56.9％-95.0％and 77.9％-98.4％,respectively.Of these sequences,the 5'-UTR and 2AB gene of HaiMen-SJH strain was significantly different from other sequences,and belonged to an independent branch in the genetic evolution trees.According to the results of epidemiological survey,the infection of CEV was widespread in most areas of Jiangsu province,and the epidemic types and situation varied in different areas.This study will enrich the epidemiological data of CEV in China,and provide the-oretical basis for the targeted prevention and control of new enterovirus infections in sheep.
